Handling
the
Lube
Oil
1) When handling and storing lube oil,
be
careful
not
to
allow
dust
and
water
to
enter the lube oil. Clean around the
filter
port
before refilling.
2)
Do
not
mix lube oils
of
different types
or
brands. Mixing may cause
the
chemical characteristics
of
the
lube oil
to
change and lubricating performance
to
drop
, reducing the engine's life.
Before supplying lube oil
to
the engine
and marine gear
for
the
first time,
extract
all
the
lube oil already in
the
tank. Use
new
lube oil.
3) Lube oil supplied
to
the
engine will
undergo natural degeneration with
time
even when
the
engine
Is
not
used.
Lube
oil should
be
replaced
at
the
specified intervals, regardless
of
whether
the
engine is being used
or
not.

Cooling
Water
(For
Fresh
Water
Cooling
Type
only)
It is Important
to
check
the cooling water
daily. Be sure
to
use clean
soft
water
(tap
water)
for
cooling fresh
water
.
Be
sure
to
add
antirust
or
anti
-
freeze
to
cooling
fresh
water
.
In
cold
seasons,
the
antifreeze
is
especially
important.
Without
antirust
,
cooling
perfor-
mance
will
drop
due
to
scale
and
rust
in
the
cooling
water
system
.
Without
antifreeze,
cooling
water
wi
ll
freeze
and
expand,
breaking
various
parts.
For
your
reference,
antifreeze
mixed
with
antirust
is
now
avail-
able
in
the
market.
